Version RR Coilover System

The Ksport Version RR Coilover System (CNS090-RR) is a high-performance suspension upgrade engineered exclusively for road racing applications. This system is designed with aggressive spring rates and precision valving, tuned to deliver maximum handling performance. Compared to street-oriented coilovers, the Version RR features stiffer spring rates, stiffer valving, and a 20–30mm shorter shock stroke, providing the acute reaction and responsiveness demanded by competitive motorsport environments. Key features of the Version RR system include a 36-level damping adjustment, allowing for simultaneous compression and rebound tuning via a single knob for quick adjustments between sessions. The monotube shock design separates oil and gas within the cylinder, ensuring superior heat dissipation, finer damping control, and reduced risk of aeration and cavitation compared to twin-tube designs. Pillow ball upper mounts, available on select applications for both front and rear, help preserve OEM suspension geometry while delivering a direct, communicative feel for improved driver feedback. Furthermore, these pillow ball mounts on select applications enable camber adjustment without the need for a separate camber kit. Adjustable lower mounts are a hallmark of this system, allowing for height adjustment without sacrificing suspension travel, unlike designs that reduce stroke when lowered. The spring rates for this specific kit are 14 kg/mm for the front and 14 kg/mm for the rear. The front upper mounts are pillowball with camber adjustment, while the rear upper mounts are aluminum with no camber adjustment.
